New law will legalise marijuana in Canada, but it wont mean you can take it to states where pot is legal.

Maine legalized recreational marijuana in 2017, but Johnson said it hasn't gotten any easier to leave the state with weed.

And while Canada will soon pass legislation to make recreationalcannabis legal, he doesn't think going north will be any simpler.

"That's going to be a difficult part," Johnson said. "The federal government on either side runs the border."

According to a Canada Border Services Agency spokesperson, importing cannabis and cannabis products will still be prohibited under the proposed new law.Jennifer Morrison said in an email that a valid permit issued by Health Canada will be needed to do so.

Going south won't be any different. While weed will be legal on both sides of the border, Calais's port director with U.S. Customs and Border Protection said it will be business as usual.

"The change in legislation on the Canadian side is not going to affect the way that we enforce the U.S. federal laws," said Corey McPhee.

He said under current U.S. federal policies, marijuana is prohibited from entering the country, so border agents will continue to follow those rules.

McPhee said marijuana is seized on a daily basis at the border, both in recreational and distribution amounts. His agency has been working with Canada Border Services to prepare for the coming changes in Canadian pot laws.

While there might be a bit of a learning curve with public knowledge at first, McPhee said he wasn't concerned.

"Our people are well-versed in how to handle it," he said.
